Unreal Engine 4.12 Preview 5


Unreal Engine 4.12 gets one step closer with the release of preview 5.  Of course this is a work in progress build, so don’t use it in production.  Preview 5 adds some new features including foliage scalability, a new animation node, a pixel inspector tool ( click a pixel on screen to visualize the material and rendering state that made that pixel happen ).  Of course there are several fixes in this release as well:


Important Known Issues

  • For deployment to additional platforms such as Android, iOS, HTML5, Linux, and TVOS you must have the optional “Editor symbols for debugging” installed. This is available via the Launcher by selecting “Options” on the 4.12.0 Engine slot. This is a transitional phase to new functionality, and the workflow will be improved in an upcoming release.
  • Google VR (Daydream) doesn’t work in the Launcher release, but is functional via Github (UE-31186)
